@pkfegroup: Here's the thing.  The best pieces of advice that I can give you are: First - You can't change his family or how he feels about his family.  If his mom wants to get back in touch, then she knows how to dial a phone or write a letter/email/whatever.  If she is doing it through his sister/her daughter, then she isn't really ready.  It is a good sign that she's evolving on the issue.  And your bf will do what he needs to do for his own sanity. Second - You can sit down and tell your bf how you feel.  (a) that you are mindful that you lost your dad and it had an emotional impact on you; and (b) you support him in whatever he decides is best; and you won't bring it up again or nag him. She doesn't have his number since they haven't spoken in so long, nor an address of any sort.

I wouldn't necessarily call myself a chubby chaser, but I do like more bigger and stockier chubby guys with meat on their bones.
